Regional Strategy for the CENTRAL COAST – 2012

This Regional Strategy can help land managers improve their coordination of invasive plant management at a multi-county scale, while providing the basis for future funding proposals. It is derived from local knowledge and CalWeedMapper’s Management Opportunity Report at calweedmapper.calflora.org. Species were selected from Cal-IPC’s statewide Invasive Plant Inventory. Please submit weed location data to Calflora and alert your WMA and Cal-IPC of new potential wildland invaders in your region. Send questions to mapping@cal-ipc.org or call 510-843-3902.


I. Eradication targets. Land managers will work together to eradicate all populations of these species in the region within five years. These are intended to be integrated into local strategies, if appropriate, without replacing existing local priorities. *Species may be removed from the eradication list, pending more information.

NEXT STEPS

I. Eradication targets: Make the eradication effort “grant ready” and apply for funding to implement it.

  • Train. Consult Central Coast Eradication list on Calflora for photos and information. Print and/or download to smart phone. Train staff to recognize species.

  • Verify “Q” quads. Check for CalWeedMapper “Q” quads, resolve whether the species is present, and edit quad data. 

  • Map populations. Map populations and upload data to Calflora.

  • Estimate funding needed. Use Eradication_Workplan.xls to note the treatment approach and estimate the funding needed for eradication.

II. Surveillance targets: Detect these species immediately if they show up in the region.

  • Train. Consult Central Coast Surveillance list on Calflora for photos and information.  Print and/or download to smart phone. Train staff to recognize species.

  • Survey. Include these species in survey activities.

  • Respond. If species is detected, submit data to Calflora, alert the WMA, and respond to the population as an EDRR target.

III. Outreach species: Build public awareness of early detection targets so the public can report sightings.

  • Develop materials. Create outreach materials and distribute to the public.

  • Publicize. Use the media to get the message out. Leverage local successes.

  • Educate. Integrate information into presentations, such as from Master Gardeners.

IV. MONITOR NEW OCCURRENCES:

  • Respond. See new occurrence reports of surveillance and eradication species in your area by accessing the Calflora Observation Hotline set up for your region. Collaborate for rapid response to these new occurrences!

Additionally, you can track new occurrence reports of Cal-IPC Watchlist species and Cal-IPC Inventory species in your region.  All Inventory species were evaluated for the region’s strategic plan but the Watchlist species were not, and could become surveillance or eradication targets.
